<p>这个QML模块包含一个用于Qt Quick的粒子系统。要使用这些类型，请使用以下行导入模块:</p>
<pre class="cpp">

  import <span class="type">QtQuick</span><span class="operator">.</span>Particles <span class="number">2.11</span>

</pre>
<p>有关如何使用该系统的简单概述，请参见<a href="qtquick-effects-particles.html">使用Qt Quick Particle系统</a>。</p>
<p>有关性能特性的详细信息，请参见<a href="qtquick-particles-performance.html">Qt Quick粒子系统性能</a>。</p>
